Mr. Rohrabacher said little after the meeting other than that Mr. Assange repeated his denial that the materials he obtained and made public did not come from the Russians, but claimed he had more information about what actually happened that he intended to share with President Trump.The “common wisdom” in Washington circles is that the Russians were responsible for illegally hacking into the DNC computers during the campaign and leaked the emails thus obtained through WikiLeaks, but recent revelations suggest that there is at least a possibility that the “common wisdom” is dead flat wrong. If it is wrong and can be proven, the charges of “collusion” so dear to Mr. Trump’s opponents could collapse.

The Nation magazine earlier this month published a lengthy report on the conclusions of a number of intelligence analysts who have looked at the available evidence and concluded that it would have been physically impossible for the Russians to have done what Mr. Trump’s critics allege.
